[QUOTE="NDMstang65, post: 4439279, member: 544576"] Hi Kyle! How about this. Show me a real world frequency plot of the LMS driver in a car. (....i've got a coil that somebody wanted a recone done and it is 3.2" long 4 layer...just a fyi) I'd bet money that you will have a SHARP drop off above 55Hz or so. There's a reason why we don't do huge coils like that, most of which is because many people do not have a very solid component system that will play down to 50-60hz with authority to keep up with a woofer of that nature...but whatever. I'm not reading your book, i've had one of the woofers..i know what it is, and what it is not. Ps: If you are only approaching the same motor strength as a daily gapped BTL with far more material than the BTL, by using a modded 4hp to get the Qts back down below .72... that tells me that you aren't doing something right. Eh, i know nothing. All I do is spin records. [/QUOTE]
